To all whom t may concern.'

Be it known that 1, WALTER J. BEHN, a citizen of the United States of America, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful mprovements in Door- Checks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a door check, and the primary object of my invention is to provide positive and reliable means in a manner as hereinafter set forth, for checking or limiting the movement of a movable member, as a door, relative to a stationary member, as a door frame or pillar, said means disposed so as to equally distribute stresses or strains that may be incurred by a sudden movement of the movable member relative to the stationary member.

Another object of this invention is to provide a door checking device that Will be concealed when the door is closed, and it is in this connection that a door checking device may be advantageouslyfused in connection with the doors of an automobile body, to limit the opening movement of the doors and prevent the automobile body from being injured or marred by a door suddenly conta-cting therewith.

A further obj ect of my invention is to provide simple, durable and inexpensive door check including a member that may be easily and quickly installed-and adjusted to hold a door in a desired open position.

The above and other objects are attained by a mechanical construction possessing advantages that will hereinafter appear as the invention is better understood, and reference will now be had to the drawing, wherein- Figure 1 isan elevation of a portion of the door frame and door provided with a checking device, showing the door in open position2 and Fig. 2 is a horizontal sectional view of the same.

1n the drawing, the reference numeral 1, denotes by way of an example, a stationary member as a door frame or pillar and connected thereto, by hinges 2 or other pivotal means is a movable member 3, as a door.

The members 1 and 3, intermediate the hinges 2, have the confronting faces thereof provided with openings 4 to receive tubular sockets 5 having peripheral Hanges at the j inner ends thereof, so that 'said tubular sockets may be fixed relative to the members 1 and 3 b nails 7 or other fastening means. The tubu ar sockets 5 have the inner walls thereof screwthreaded, as at 8, to receive eXteriorly screwthreaded nipples 9 andsaid nipples have the outer ends thereof provided with notches or recesses 10 so that a ySpanner wrench or suitable instrument may be placed in engagement with the outer ends of the nipples 9 for rotating and adjusting the same in the tubular sockets 5,.

Connecting the nipples 9 is a short length of cable 11l constituting a Hexible check member that is loose within the nipples 9 and has heads -12 to engage the inner ends of the nipples and thus limit the movement of the member 3 relative to the member 1.

With the cable or checking member 11 in i the nipples 9, the ends of the cable or checking member may protrude from the inner end of the sockets 5, and in this manner the cable or checking member will be concealed within the socket members 5 when the membei` 3 is closed or alined with the member 1.

Considering the door check connection with an automobile body, it is possible to adjust the nipples 9 so that the door 3 will have a limited openingmovement relative to the door frame or automobile body 1. Since the automobile body walls are generally hollow, also the doors, there is plenty of clearance for the ends of the cable ll when the door is closed, but should the automobile body have solid walls and a solid door, then it is only necessary to make the openin s 4 of greater length than :the socket mem ers 5, thus providing suliicient clearance for the ends of the cable when the door is closed.

The adjustability of the nipples 9 permits of cables 11 of equal length being provided for various kinds of doors and the nipples adjusted so as to properly limit the movement of the door relative to its support. 1n the latter instance, the tubular sockets 5 may be reversed and the flanged ends thereof countersunk in edge of the door and the edge of the door frame 1.

Coiled compression springs 13 may encircle the check member 11, between the nipples 9 and the heads 12, said springs being suitably attached to the nipples so as to rcmain in the socket members 5. rThe springs 13 will prevent rattling of the heads 12 within the socket members 5 and tend to cushion an extreme opening movement or" the door. ln some instances one of the springs may be dispensed with.

l1 attach considerable importance to the tact that the checking member 1l is non extensible and consequently will properly hold a door after having once been set.

lll/'hilo in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such changes, as in size, shape or manner or" assemblage, as tall within the scope of the appended claims.

lJl/'hat l claim is:-

1. The combination of a stationary member, a movable member hinged thereto, sockets set in the inner faces oit said stationary and movable members and protruding therethrough with the ends of each socket open' and the inner walls thereotl screwthreaded, iianges on the inner ends or said sockets connected to the inner faces ot said members, nipples screwed in. said sockets and having the outer ends thereof notched to facilitate adjustment ot said nipples in said sockets, a cable extending from one socket to the other with its ends loosely extending through said nipples, heads on the ends of said cable and free to move with said cable and out of the inner ends ot' said sockets, and coiled springs normally in said sockets loose about the ends olf said cable between said nipples and said heads, and adapted to cushion said heads relative to said nipples when said movable member has an excessive opening movement relative to said stationary member.

2. The combination ot a stationary member, a movable member hinged thereto, sockets set in the inner faces of said stationary and movable members, the inner walls thereot screwthreaded, nipples screwed in said sockets, a caible extending from one socket to the other with its ends loosely extendinv" through said nipples, heads on the ends or' said cable and tree to move with said cable and out of the inner ends oi" said sockets, and springs normally in said sockets between said nipples and said heads adapted to cushion said heads relativ to said nipples when said movable member has an excessive opening movement relative to said stationary member.

I-l. 'l'he combination oiu a stationary member a movable member hinged thereto, a socket set in the inner face of one of' said members, the inner wall thereof being screwthreaded, a nipple screwed in said socket, a cable having one end secured to one oic said relatively movable members and the other end loosely extending,l through said nippleSv a head on the end ot said cable tree to move with said cable, a coil spring about the end ot said cable and between the nipple and the head and adapted to cushion said head relative to said nipple when' the movable member has an excessive opening movement relative to the stationary member.

ln testimony whereof I alix my signature in the presence of two witnesses.
